FERGUSON ANDCHARLES SHOGKENCY, OF LIMA, OHIO FLUE MARKER Application filed February28, A1930. Serial No. 432,276.

This invention relates to an appliance which is hereinafter referred tobrieiy as a flue marker, and it has more particular reference to anappliance in the form of an attachment to be used on a conventional fluecutter, wherein said appliance is especially designed and constructedfor marking rotary flues and boiler tubes.

In carrying the invention into practice,

i0 we have evolved and produced a structure which is believed to be anovel contribution to the art, a structure which is original andcharacteristic in that it embodies appropriately related details foraccomplishing the desired results in a practical and feasible manner.

Furthermore, we have developed a novel structural organization of partswhich are co-related in a manner to provide a structure which issusceptible of accurate manipulation, and which is otherwise dependablein fulfilling the requirements of an appliance of this class.

In the drawings:

Figure 1 is an elevational View showing the complete appliance asconstructed in accordance with our invention.

Figure 2 is a vertical sectional view at right angles to Figure 1.

Referring now to the drawings by reference numerals, attention is iirstcalled to the character 3. This designates an existing oscillatoryoperating shaft on a conventional flue cutting machine (not shown). Inaccordance with the present invention, we

provide an operating arm including a substantially vertical portion -land a horizontal portion 5 at the upper end. The lower end portion ofthe part 4 is constructed as at 6 to provide one-half section 6 of theclamp which embraces the shaft 3. The complemental or companion sectionof the clamp is indicated at 7.

Attached to the upper end of the horizontal part 5 is a U-shaped carrierframe 8.

The upstanding arm portions of this frame are provided with bearingholes to accommodate a rocker shaft 9. On one end of this shaft is arocker arm 10 to which a ..return coiled spring 1l is connected. The

-o'ppos'ite 'end ofthe spring is fastened 'to an outstanding bracket 12on the frame.

The *rock `sha-'Aft 'includes a substantially rectangular :portion '13constructed to *sup- :port a :plurality of horizontally f'alined )l5brushes generally designated by fthe numeryals 14. These ybrushes lareremovably held 4in'placeby the 'set 'screws 15. The brushes areprojected normally in a vhorizontal plane fed-'o'n'the end portions ofthe rock shaftso V79 as "to bese'lf levelling. The supporting arm "4,fthe fra-me '8,-andthe :receptacle 17, with the ibrushes fand rocklshaftfc'onstitute "a :unit vrwhich 1is :swung vbythe shaft 3 toward andawa-y rfrom aflue F, intoloperative,-xnarking 'position or into*inoperative position which is indicated by the dotted lines in Figure2. The brushes I14fare-normally :maintained in a horizontal markingplane, -but they swing to a downward vertical position and dip into theflue in the receptacle 17 to re-prime them with marking fluid, when theunit moves into the inoperative position shown by the dotted line inFigure 2. The link 16 operates or is operated to swing the brushes 55 14into the pan 17 as the unit is moved from operative to inoperativeposition.

Persons skilled in the art to which the invention relates, and personsfamiliar with conventional flue cutting machines will be able toappreciate the novelty of this appliance, the ease with which it may beattached to the conventional filing machine, and as well as otherfeatures and advantages accompanying the invention. Consequently, a morelengthy description is regarded as unnecessary.

It is to be understood that minor changes in the shape, size andrearrangement of elements which fall within the field of inventionembodied in the accompanying claims may be resorted to in actualpractice if desired. d

We claim:

1. In a structure of the class described, in combination, an oscillatoryoperating shaft, a liquid containing receptacle sup-y ported thereon andbodily movable therewith, and a multiple brush assembly associated withthe pan and movable With said pan and also movable independently "of thepan for replenishing purposes.

2. In a structure of the class described, in combination, an operatingshaft, a frame connected to said shaft, a self-levelling liquidcontaining pan mounted on said frame, a rock-shaft mounted on saidframe, a marl:- ingL brush carried by said roclr-shaft and cooperableWith said receptacle.

3. In a structure of the class described,

an operating shaft, an arm rising therefrom, means fork clamping saidarm on said shaft, a frame carried by said arm, a selflevelling fluidpan carried by said frame,

marking brushes mounted on said frame and swingable into said pan, andoperating means for said brushes.

4. In a structure of the class described, in combination, a U-shapedframe, a rock shaft mounted for-rocking motion in bearing holes in thearms of said frame, a rocker arm on said shaft, a depending actuatinglink for said rocker arm, a plurality of removable marking brushescarried by said rock shaft, a return spring for maintaining the brushesnormally in a horizontal plane, hangers carried by said pan andsuspended from said rock shaft to render said pan substantiallyself-levelling, and means for mounting the vframe on an oscillatoryoperating shaft.

'In testimony whereof We affix our signatures. Y y
